Be it known that I, DAVID BRIGHTBILL, a citizen of ,theiUnited States,anda resident of the city off Lebanon, county of Lebanon, and Sta-te ofPennsylvania,-have invented certain new and useful ImprovementsinSausage-Stufiing Machines, of ,which the following is a specification.v

The invention relates tofsausagestuiing machines of the rotarycontinuousfeed type, wherein the minced meatis depositedrin a forcingchamber, and `thence continuously conveyed and driven outwardly underpres-v sure through a. suitable Voutlet into the skins. The main objectof the inventionis to lsubply a sturdy, durable and efiicient device ofthis kind, made up of relatively few, strong and simple parts, allcapable ofecononiic production. Y e Y t c Another object of theinvention-is toprovide means in connection with a machine of this typefor. opening the forcing chamber in such a manner as to completelyexpose the interior Vparts and surfaces thereof so that such parts andsurfacesas well as the meat driving and .conveying mechanism .within thechamber, may be quickly and easily accessible for the purpose ofcleaning the Vsame and applying rustlpreventatives thereto. At thepresent time the making of sausage, bologna and other. kindred foodproducts is almost' universally@ conducted under the restrictions andregulations of pure food and other sanitationlaws, and a customary andusual requirement of such laws withl respect to the usel of stuflingmafl chines is that all the mechanism and partsV thereof which comeinto-,contact withl the meat be frequently washed and cleaned, and allparticles ofmeat or other substances vadhering thereto be scraped -otiVori otherwise removedfthe rules in some instances calling for the use ofboiling water o r other V purifying 'and disinfecting liquids orsolutions, In view of these conditions and re'- quirementsit has becomedesirable that the enclosed members of these machines, such as thepressure chamber or casing .in theJ present embodiment, be so made Vastobe, capable of beingreadily and quickly laid open and the meatconveying elements so far as possible either removed. therefromV orrendered completely l'accessible without the exercise of undue skill oreffort. lt is accordingly. one

of the purposes of this invention yto this requirement by providinga-Mremovable wall for the pressure chamber, said wall lbeing outwardlyhinged Yto. the chamberca-sing in the manner of a door plate, and ,thesame carrying therewith .one of the 'meat conveying members, so that thewall ,may be readily removed fand 4.again replacedfon theehamberhwithout [the necessityoffdey taching the same lbodilyfrom themachine and that the meat conveying members may be thrown out oflengagement and again "re-- turnedto their normal cooperative positionsby a few very simple movements on lthe part of the operator.` i Y Y iOther purposes and objects ,of theinvention will appea-rfrom thefollowing description taken in connection withY the .accom-l panyingdrawings in which Figure l is a'front elevational view of a machineembodying myfinvention. 2 is .a vertical sectional view lthereof online2-2 vof Fig. l.. Fig. 3v is a similar view to that 'shown in f Fig. 2,'showing the front wall of the pressurechamber removedand throwndownwardly onl the hinge to remote open position. Fig. t is a viewsimilar to Fig, l, likewise showing theV4 pressure cham-A ber wall inremote open position, Figl is a side elevational View with aportionofthe driving mechanism `broken away,V to show the` gearing, and FiguresyGland?? are plan and side views respectivelyof a lunette constitutingone of the meat conveying parts.

YReferring' more particularlyfto draw# ings, the numeral 8 indicates abaseorframe kwhereon. is supported and secured, as by bolts 9, the'casing l0, having an outwardly l flared upper portion 11 in the .shapeofv a vhopperor fun-nel, and a restricted lower portion made withsubstantially .-vertical side wallsl and 2l, front and rear walls 2 5and 26,.and a bottom l27, formingla pressure chamber 11i. Anl outletnozzle` 28v is pro; videdin the frontY wall Qyadj acent thebottom 27 forthe conveyance of` the meat outwardly from the chamber into the,skins,the mouth ofthe nozzle being externallythrea'ded asat'29 for theadjustmenttheretofof a spout 30 of the kindv common-'ly used for thispurpose.v nallyfformed'onthe 'sidewalls lfafnd 21, is a Journaled inhubs 15,'15fe`x'terg' horizontal shaft extending i celv'ffluy throughthe chamber and slidably secured thereto by means of a key 65 is thecylindrical'rotor or drum 17 having one or more radially extending wingsor teeth 18 designed to loosely mesh with a lunette 19 disposed forrotation in. an appropriately formed 'grooved seat 2O extending acrossthe inner face of the frontV wall immediately above and in substantialalignment with the upper wall 31 ofthe nozzle outlet, said lu` Vnettebridging and effectually sealing the -spacebetweenthe front wall and thedrum against the passage of the meat.

' In fthe present inst-ance theV lunette is formed byl cutting a groove32 ofsubst-anj tially semi-*circularY cross-sectional voutline in ashaft 33, the groove being of sufficientv lon- .oitudinal extent vtoaccommodate the teeth, andthe same terminating short of the ends of theshaft whereby the terminal portions of the shaft are adapted tobejournaled in bearingsfOrmed inhubs 34 and 35' extei` nally providedonopposite sides of the casing, the end 36 of the shaft being squaredand abutting against the closed'V end 37 of I the hub 34 to preventlateral dislocatiornand the opposite end 38 thereof projecting throughthe hub and havingI a central flattened rextension forming acouplingmember 23. ,A short drive shaft 24, journaled in v .a bearing 22onan arm139 secured to a bracket 40 on the sidewall 21 of the casing,carries at its outer. end a pulley 41 for the transmission of rotarymovement to the ma'- ichine, as by a drive belt 43 connected with a Ymotoror other source of power, a slot 44 Vcentrally cut in the inner endof said shaft forming a coupling member adapted to re.-

ceive and co-opera-te with the coupling member 23 of the lunette'shaft33, and a pinion 45 'on the Adrive shaft engaging a suitable gear '4.6on thedruml shaft 16. The pinion 45 and gear 46 are `appropriatelyproportioned to so control the relative rotative :movement of the drumand lunette as to cause the teeth 1,8 of the former tojmesh with thegroove 32 of the Vlatter'and thus permit the teeth to freely pass theVabut'- ment constituted by the 'lunette against the passage 'of theinea Forthev purpose of permitting .quick and i easy vaccess ltoitheinterior of thev machine I VVVfor the purpose hereinbefore referred to,the

Y made in the form of an integral plate sepa-V front wall 25 of thecasing together with the adjoining frontwportions of the side wallsthereof carrying the bearing hu'bs 34 .and 35 of the lunette, are, inthe present invention,

rate and apart from the'casing proper, lso'as to vbe bodily removabletherefrom, and, as such, are hingedlyattached to the' lower part of the.casing 'by means of a hinge pin 49 passing through perforated'lugs'orears 47', 47 and 43, 48 depending from the 'lower parts of the casingand the wall respectively.

The wall 25 is thus adaptedto operate in the manner of a door plate tocover and close the front of the casing, andY convenient meansforsecuring it tightly in working position against the casing areprovided, which `V means are ofsu'eh a characterv as to enable the wallto be quickly and conveniently un# fastened and removed or restored toplace and again made fast. In the present instance lthe securing meanscomprise swinging bolts, 50, 50, each of which is mounted upon a pivot51 between a pair of lugs 52, 52,

on the exterior ofthe side walls 13 and 21,

the front wall 25 having laterally projecting lugs 53, 53, :wi-th opennotches 54, 54, to

receive the threaded stemsofthe bolts, ,wifng nuts 55, 55,beingjprovided on the stems forV tightly" drawing Aup the plate againstthe casing.

k*Figures 1 and 2 show the casing as Vrit appears when closed lwith thebolts 50,Y 50 in` -their normalpositions, the stems thereof occupyingthe notches 54, 54 on the edges of the wall'plate, and the nuts 55, 55tightened up against the casing, the wall plate bei-ng thus lockedandclamped sec'urely'in place. It willbe observed ythat the'form ofsecuring means illustrated is especially contrived and adapted lto-withstandthe' internal presf sure exerted'against the front wall25,jto

retainthe lunettein its" appropriate operative position with respect tothe drum, to prevent the escape of meat from the :casi-ng Athrough thejoint betweentherllatter and the 'wall plate, and to vretain the'lunette' be free to be swung forwardly land downf wardly on the'h-ingepin 49 to open-position as shown in Figures 3 'and 4. When the wallplate is insuch open position, the lunette shafty may, with very slightexertion; be bodily withdrawn from its seat and bearings by simplypulling it out its projecting end, and after such removal the seat andbearings of the vshaft and all linterior surface' of the wall plate maybe easily vreached and thoroughly washed, scraped and cleaned.' The drumV17 will also, in *i such open position of the wall plate, be almostentirely exposed and the interior walls and bottom of thel casing made-accessible for cleaning.

there being but slight.clearanceallowed be? v tween the teeth and theinnen faceof the t wall, andfitv-is likewise desirable thatthe teeth 18ofthe `drum be made relatively narrow in cross section andzbe. otherwiseso formed as to mesh :loosely jwith the lunette, and so vthat the teethin passing` throughfthe crescent, while 4constantly contacting-transversely along one line, will occupy only a limited portion viofythe; space afforded by the groove-thus ob-viating the tendency of theteeth to crush and' compress the meat whichicollects, inl thezrgrooveand enabling the same to be swept, rather thanV squeezed, out.: v Tofacilitate; the more'thoroughv ,cleaningthe pressure chamber, aszmayoccasionally be desired, provision isf-mader forthe removal of thedrumand the drum shaft 16 from the machinewthout v,takingioff the gear Wheel116v or'disturbing thesame in its meshed relation `to-the pinion-115Yand* for permitting theV prompt and accurat'erestoration of said partstoitheir proper engaging positions Vwith relation to. the lunette 33.The means providedE for this purpose comprise a circular fla-nge 60concentrically formed on the inner side ofthe gear 46, said ange beingadapted'to lreceive the outer end of the hub 1:5 therein, and having anexternal peripheral groove (31 for the free reception of a retainingfinger 59 sef cured to the hub 15 by a bolt 64. A set screw 63 isthreaded in a hub 62 formed on the opposite side of the gear and isadapted to enter a shallow` socketA (not shown) in the shaft to securethe gear in appropriate position to the shaft, while a keyway 66 in thelatter accommodates the key 65 secured to the drum and extends outwardlytoi the end of the shaft fopposite'- 'the' gearvto lpermit the endwise'Withdrawal ofv the shaftvthrough the gear 16. l/Viththis constructionit vwillbe clear that looseningthe setlscrew '63' and elevating itsii-'Iiciently to clear fthe shaft, the latter may be i pulled 'out andvremovedV from themachine,
